5.17.2.C. Image Transformations

Try these first

1. 1.

   What does NDVI represent in remote sensing?

   Hint

   Remember that NDVI involves both near-infrared and red light.

2. 2.

   Name one application of image transformations in agriculture.

   Hint

   Think about how farmers assess their crops.

3. 3.

   What operation does NDVI primarily rely on?

   • Only Red Reflectance
   • Only Near-Infrared Reflectance
   • Both Red and Near-Infrared Reflectance

   Hint

   Think about the components of the NDVI formula.

4. 4.

   True or False: VIs can only be applied in agricultural studies.

   • True
   • False

   Hint

   Consider the broader applications of these indices.

5. 5.

   Evaluate a scenario where NDVI might indicate a false reading for vegetation health. What could be the possible reasons?

   Hint

   Reflect on factors that might distort image quality.

6. 6.

   Analyze how you would apply image transformations in a mixed land-use area. What considerations must you take into account?

   Hint

   Think about complexities introduced by different land specifications.
